Les options de conduits souterrains\u00a0:<\/strong><\/p>\n

Conduit en PVC \u2013 L\u2019un des types de conduits les plus utilis\u00e9s pour les installations souterraines.<\/p>\n

Fabriqu\u00e9 en tuyauterie rigide en polychlorure de vinyle (PVC). Durable, r\u00e9sistant \u00e0 la corrosion et relativement abordable. Disponible en diff\u00e9rentes tailles.<\/p>\n

Conduit en PEHD \u2013 Fabriqu\u00e9 en poly\u00e9thyl\u00e8ne haute densit\u00e9 (PEHD), il est flexible et plus facile \u00e0 installer que le conduit en PVC rigide. Souvent utilis\u00e9 pour les applications d\u2019enfouissement direct. R\u00e9sistant \u00e0 la corrosion et tr\u00e8s durable.<\/p>\n

Conduit en acier \u2013 Le conduit en acier rigide galvanis\u00e9 offre une durabilit\u00e9 maximale sous terre, mais est plus lourd et plus co\u00fbteux \u00e0 installer que le PVC ou le PEHD. Tr\u00e8s r\u00e9sistant \u00e0 la corrosion.<\/p>\n

Conduit en fibre de verre \u2013 Non m\u00e9tallique et r\u00e9sistant \u00e0 la corrosion. Bonne alternative lorsque des propri\u00e9t\u00e9s non conductrices et non magn\u00e9tiques sont requises. Plus cher que le PVC.<\/p>\n

ENT (tuyaux \u00e9lectriques non m\u00e9talliques) \u2013 Tubes flexibles en PVC utilis\u00e9s comme alternative peu co\u00fbteuse aux conduits rigides, g\u00e9n\u00e9ralement pour les courts trajets souterrains. Plus facile \u00e0 installer que le conduit rigide mais offre moins de protection physique.<\/p>\n

Conduit pr\u00e9-courb\u00e9 \u2013 Disponible pour PVC et HDPE. La conception pr\u00e9-courb\u00e9e facilite l'installation le long d'alignements courbes sans avoir \u00e0 former de coudes sur le terrain.<\/p>\n
